  • Utilize Docker for containerization and manage test platform services in cloud environments.

  • Proven experience in leading test frameworks and defining comprehensive test strategies.
  • Experience developing and maintaining automated test frameworks in Python, using Playwright, TypeScript, or similar tools in other programming languages such as Java.
  • Hands-on experience integrating AI tools, LLMs, or AI-driven testing methodologies into daily QA workflows and CI/CD pipelines, including familiarity with prompt engineering and using AI assistants to streamline testing processes and automate repetitive tasks.

  • Proven experience with AWS or GCP, and with Docker, Kubernetes, plus event-driven architectures using Kafka or similar tools; familiarity with CI/CD tools such as Jenkins, GitHub, or GitLab.
  • Excellent analytical and problem-solving skills.
  • Ability to work independently and collaboratively in a fast-paced environment with globally distributed teams, with a strong technical background in software automation development and a big-picture, can-do approach.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
